Cerebrospinal fluid
Summary of Cerebrospinal fluid
Daily, 500 milliliters of cerebrospinal fluid is generated by the epithelial cells of the choroid plexus. After flowing through the ventricles and the subarachnoid space, cerebrospinal fluid is gradually recycled into venous blood by one-way bulk flow through the arachnoid granulations. Cerebrospinal fluid is the solution that provides a protective, controlled environment for the brain.
